The Buluan Lake (English: Lake Buluan ) is an inland lake on the Philippine island of Mindanao . It is located southeast of the municipality of Buluan on the border between the provinces of Maguindanao and Sultan Kudarat . The lake covers an area of 65 km² in the southeastern part of the Central Mindanao Basin. The Buluan River forms the main inflow and outflow of the lake. It is located in the water catchment area of the Rio Grande de Mindanao . The lake marks the southeastern end of the Ligawasan river marshes .
The aquatic vegetation is dominated by thick-stalked water hyacinth ( Eichhornia crassipes ), water spinach ( Ipomoea reptans ) and water lettuce ( Pistia stratiotes ).
The fish stocks mainly consist of the rohu ( Labeo rohita ), the snakehead fish Channa striata , tilapia ( Tilapia sp ), the goby Glossogobius giurus , the carp ( Cyprinus carpio ) and predatory catfish ( Clarias sp ). These fish species are also used for commercial fishing. The climbing fish Anabas testudineus is at home in the sea area, as is shrimp of the genus Macrobrachium sp .
The lake was declared a Lake Buluan Game Refuge and Bird Sanctuary on December 1, 1926, covering an area of 63 km².
